The invention is for a portable combined internal combustion engine head support and valve spring compressor and is more particularly adapted to use in the operation of grinding the valves of an internal co nbustion engine of the valve-in-head type.

The primary object of theinvention is to provide a device of thecha racter indicated which c'an'beeasi'ly and readily moved from place to place in a machine shop and placed in any position relative to the engine of an automobile to receiveand support the engine headfor repairs and is more particularly adapted to the support of'the engine head for "the purpose of grinding and setting the valves. Y

A further object of the invention is toprovide a support for an engine head whereby a mechanic may stand in one position and work' on any part of the engine head without moving the support or himself moving in order to have ready access to all parts of the engine head. 7

A further object of the invention is to pro videa-ninternal combustion engine head support which will obviate the necessity of a mechanic removing the'engine head from the enginefblock' of an automobile and carrying the same tot-he work bench which, maybe, and oftenisat a remote point from the automobile in the shop thus saving both time and labor. A still further object of the invention is to provide an internal combustion enine head support that will be of such con to provide a device of the character stated which will be simple of operation, economical-ofmanufacture, and efficient in 1ts functions Applicant is wellaware of the fact that struction as to render it light, easily moved portable work supports of various kinds and for various purposes for machine shops are old but does not know and does not believe that there has ever been a portable combined internal engine head supportand valve-spring compressor made or used which embodies the combination of elements for the performance of the functions capable bythe device described in the following specification and illustrated in the accompanying drawings which are made a part of this specification and in which I In the drawings Fig-1 is a. front elevational view ofthe invention partially in sectiOI-l.

For a more comprehensive and clearer .understanding of the invention reference will now be. made to the drawings by reference numerals using numerals for V the, various parts and elements of: the device. Like r'efei'ence numerals indicate like, parts 'or elements throughout the several figures of the drawings. 1 e 1 Reference character A indicates the sup; porting frame generally which may be made of any suitable material, such for instance, as. cast iron or steel andfis provided with supports or standards 11 and 12- which are provided with bases 13-and1iwhich extend, toeither sideof thestandards for the purpose'of providing a stable support for the device and to prevent tilting. Standards 11 and 12 terminate at their upper ends inbrackets 15 and 16 for the support thereon of a transfer board 17 having upwardly extending bosses 18 thereon-which bosses are for the purpose of receivingthe downward thrust of the valve stem head when pressure is applied by the plunger on the valve spring for the purpose of removing the retaining key for holding the valve stem spring under initial pressure and for the further purpose of spacing the, engine head from the. transfer board 17 inorder to provide a clearance for r V the fingers of the mechanic when placing the head on the transfer board or securing a hold on it to remove it therefrom. The brackets 15 and 16 are provided with upwardly extending flanges1'9 and 20 at their outer lateral edges respectively for limiting the movement of transfer board 17 longitudinally of the work support. springing upwardly from the brackets 15 and 16 and preferably adjacent the rear edge thereof is ayoke indicated by the reference character B, generally the yoke is composed of uprights 21 and 22 which maybe secured to the rear end of bracketsv 15 and, 16 in any suitableman ner-though preferably by screw-threadlng the r 1 ends of the uprights for the reception thereon of nuts as clearly shown at 23. Upright 21 is provided with offset 24 ashort distance above bracket 15 to provide a clearance for the over-hangingEportio'n or lip of an engine head a'ndf'terminatihg at its upper'end in a spanner 25 which extends transversely acrossthe support and has a free sliding'movement through the apertured-head 26 of upright 22. Upright 22.maybe secured to-bracket 16 in any suitable manner such as described with reference toupright 21. Spanner 25 has pivotally'related thereto operating lever '27 as-by shackle 28 or in any suitable way.

Operating lever 27 has depending therefrom and pivotally related thereto plunger, 29

which is provided at its lower extremity with diametrically opposite presser feet 30 for .en-

gaging the usual spring retaining cup or washer of a valve spring for compressing;

the spring to relieve the pressure on the cup or washer when the locking keymay be readily withdrawn from the valve stem and the valvelstem removed-from the engine head.

'Itwill be observed Tthat the plunger is provided with two diametrically opposite presser 1 'feetfwhich arereces'sed as at 31 .whichrecessesare for the purpose of receiving therein the valvestem of the inlet port and the valve stem of an'ou'tlet port of an engine head for the simultaneous compression of their respective springs by a single downward movement of the operating lever 27. Operating lever 27 is longitujdinall y slottedas at 32 at apoint approximately above the center of the flanges 19 and 20of'the bracket-s '15and 16 when theoper'ating leveris in a horizontal position tance slightly greaterthan the diameter of operating handle 27 from shoulder 35 of the plunger 29 to provide for a free rocking movement of the plunger with relation to the operating handle 27 in adjusting the feet 30 of the plunger to the spring retaining cup or washer of the valve stems upon which it is desired to compress the springs. The plunger 29 may be retained in slot 32 of the operating handle 27 by the insertion therethrough of a cotter pin 36 preferably having a washer 37 interposed between the cotter pin 36 and the operating handle 27. Supported by the standards 11 and 12 and below the brackets 15 and 16 is secureda telescopic pan 38 which is for the purpose of catching anything which may dropfrom the engine head supported by the device when being worked upon by amechanic such as smallparts, grease or the like. .Secured t0 the front wall of the pan 38 is provided-valve stem rack 39 having aperture 40 therethrough for. the insertion therein of the valve stems as they are withdrawn; from the engine head. This valve stem rack-maybe supported con.- tiguous tothe pan 38 in any suitable way and may be made of any suitable material. 'As

shown in thedrawings the valvestem rack is the drawings is provided with six upward 1y extending bosses for the accommodation" ,of a six cylinder engine headthereon and.

it will be noted further that the valvestem rack is shown in the drawings as. provided withv twelve apertures therethrough in staggered relation for the reception therein of the six inlet and six. outlet port valve stems. of a six cylinder engine. The six perforations nearer the front side of the rack may be used for the six inlet port valve stems and the six perforations to the rear of the rack may be used for the six outlet port valve stems, in both instances placing the valve stems, in the respective apertures in corresponding sequence to thev bosses 18 on the transfer board 17. Thus it will be seen that the mechanic will be enabled .to definitely identify the valve stem in the :rack with the port from which it was withdrawn andthereby avoid confusion and'be assured-of replactaeetaa ing each valve stem in the respective port from which it was drawn.

Intermediate the upper and lower ends of standards 11 and 12 and preferably at their approximate centers is provided adjusting .rod 41 which is screw-threaded for a portion 41 is capable of free rotatable movement for drawing or propelling standard 11 toward or away from standard 12 and thereby regulating the distance between brackets 15 and 16 in order to so adjust the lateral dimensions of the device as to accommodate the transfer board having four, six, or eight bosses for the reception thereon of an engine head having four, six, or eight cylinders as oocasion may require by reason of the engagement of the screw-threaded adjusting rod 41 with the internally screw-threaded boss 42.

Locking collars 46 and 47 having tensioning screws 48 and 49 respectively are provided for contacting with the respective ends of boss 43 to prevent the accidental movement of standards 11 and 12 with relation to each other. Crank handle 44 is affixed to adjust ment rod 41 at its outer end adjacent support 12 for rotating the rod in adjusting the standards 11 and 12 with relation to each other for support on brackets 15 and 16 of a transfer board 17 for the accommodation thereon of a four, six, or eight cylinder engine head as may be required for the piece of Work which the mechanic may have in hand. The device is provided with rollers or castors for portably supporting the frame A in order to conveniently move the device to any point desired on the floor of a machine shop.
